verting this holding device and presenting it to the open sectional mold. -After the sectional mold closes against the lasted upper, the portable holder is removed. y

The sectional mold may be held in the closed position by means of suitable levers pivotally mounted with respect to the table 11; suitable springs being associated with such levers so as to tightly clamp the sections of the mold in the closed position ,around the vlasted upper. This mechanism is more fully disclosed' in my copending applications before referred to.

As soon as the lasted upper is properly positioned and clamped in thesectioaaal mold. and the portable holding device therefor has been released, such lasted upper is ready to:` have the projecting portion or portions :1; thereof laid down. The mechanism hereinafter described' is designed to wipe and lay down the projecting portion or portions of the upper over the insole y carried bythe -last upon the upper is stretched.

The improved' wiping mechanism forming the subject of my present inventionisA duplex' character for simultarle'o'usy operation upon'the heel and'toe portions of the lasted upper, and the respective sections or portions-,ofthe same are mounted upon the'mol f-carryingA tablel 1l at opposits ends of the incid supported thereby. y I'n 'the present instance the sectional mold It? is arranged between two sets of wiping elements and mechanism toxoperate the'same; eachl of said wiping elementscomprising'a pair of blades or jawsV carried by "ai reciprocable frame which'm-ay be moved into and out of operative position with respect to thev upper. mounted in the sectional mold. Each set ol` blades orjaws is of Substantially the same character and construction,v and each pair is pivotally connected together so as tobe movable as a unit' into andout of operative position 'over the lasteduppcr,v as shown in Fig. 5. A fter they are so' moved provision is made for rocking them 'back and forth and oni `'their pivotal connections by means carried by therespective supporting frames therefor, and in'lthe presont' instance such means com-prise'movable plates reciprccr-ibl'eV in 'gui-'des longitudinally with respect tothe frames,y and operativen7 connected to' the blades `or* jaws of the wiping elements; such frames having cam slotsoperatively arrangedv connectionv until the projecting portion :c of the lasted upper has been fullylaid' down and held against the insole; the latter having been previously coated withfa suitableadhesive or cement.

By Vpreference the projecting portion :c o1' the upper 'has been notched by removing portions ofl the same, as indicated at e, sovthat` it may be laid down upon the insole withoutundue'- wrinkling or overlapping and Athereby present a substantially hat surface for the reception of a sole',l which wiped portions may or'may not' be rasped or roughened' for the reception of the adhesive or cement designed to hold-such sole in position with respect to the lasted upper and complete the shoe or other article of footwear.

In the drawings, I have shown the wiping mechanism as supported by suitable frame-work properly positioned with respect to the sectional mold in which the lasted upper is positioned; the respective frames being indicated at and 21. Each of these frames may comprise a base portion 22, upon which an adjustable support 23 is mounted; the latter being provided'v with a plurality of guide bearings or supports 24 for a pair of sliding rods 25, carrying a cross-head 26, which in turn supports a rod or shaft 27 carrying the frame which `supports the wiping elements. The rod or shaft 2'7 is arranged to rock in thel cross-head26, and may be operatively connected therewith by means of adjustable collars 28' carried by said rod' 27 and held in position by suitable set screws; said collars havinor rounded faces adjacent the cross-head to facilitate the rocking movementV of the rod 27. The frame supporting' the wiping jaws issupported in the inactive position by aroller justably carried by an' 31' projecting' from theibase portion 22, as indicated in Figs. 2 and 4. When these frames are moved! so-asl to bring the wiping elements over the moldf, they drop off the rollers 30 andare drawn down so as to bring the wiping elements into engagementwith the mold by means o1' springs 32, in the manner hereinafter described. i

The springs A32 are connected to bell-crank levers 32n pivoted at 32; one arm of' such levers being engaged by the frames carrying the wiping elements so that when 'such frames are moved to bri-ng the wiphg` elements into operativeV position overl `the mold', the bellcrank leversv will react uponI the springs and cause`- them to lower ther forward ends of said frames'. To peri-nit"y this. operation, the rod or shaft 27 supporting the frame carrying the wiper jawspassesthrough abearing 33', pivotally supported at 33e upon a-vertically adjustable post 34, which may pass. through a guide 324B carried by the' base portion 22,. through the table llyand tl'irougl'i` abracketmember secured to the underside of the latter; suclrbracket. member supporting an adjusting nut 36. By this means the post. 34 carrying the bearing 33' may be vertically adiusted to' properly position. the wiping elements relatively to upper-carrying molds of different heights'.

'I'he framesupporting'the wiping jaws may comprise a plate 40 carried at the end of' the rod' 27; such. platebeing preferably provided with sidewalls'. or,` iianges 41 and a, central block or guide 42'.A A cover plate 43` is mounted on the plate 40 over-the anges or sidewalls 41 of the same, `and may be securedli to: saidr flanges by bolts 471%. -In the" space: between these flanges and the cover plate 43, the wiping jaws and the mechanism for operating the same arel placed.

The jaws carried by themechanism at the left of the sectional mold, designed to operate upon the heet portion' of the lasted upper, are indicatedy at 45 and. 45a', -while thoseat the right, designed to act upon the toe portion of` the; lasted upper areindicated at 46 and 46a. The respective sets-tof jaws are connected together 'by pivot pins 47 and 48. Each jaw carries an upwardly projecting pin 49, preferably with a roller sleeve 49a, for ioperativerengagement" with cam slots 50 in the cover plate 43 which occupies a; xed position with respect to the plate 405'. theI relation beingsuch that@ when the jaws are reciprocated 30 whichfmay be adwill `rock or swing on their pivot pins 47 and'48, f

When the frames carrying the wiping elements are moved to operative position, they ride off therollers 30, and

lugs 40a at the side of these frames engage 'one of the arms of the respectivebell-crank levers; causing them to move kon-thei'r pivotal connection and. exert pull Suponthe springs which hold the wiping elementsin contact with the mold and the lasted upper therein; the springs providing suiicient; pressure and at the same time yielding to any inequalities of the surface engaged bysuch wiping elements.

The sliding members 51 are connectedto the jaws of Ythe respective sets of wiping Velements 59; rthe cross member beingslotted at 58a so as to permit'longitudinaladjustment of said slidingmembers 51 with respect to the same. The cross member has an upwardly projecting portion 60 to which thenrod 52A is connected; the opposite endof said rod 52 .sliding ina support 61 carried by and projecting upwardly from the rod or shaft 27. `A block'62 may be` carried by the rod 52; being adjustably held;to thel same by collars 63, secured to said rod by set screws. This block carriesla pin k64, with a roller 64a, and this roller is engaged by the, arm 65 of a bellcrank leverpivotally mounted at 66to acrossbar 67,'carriedby and secured to the pair of f sliding rods 25, mounted the guide bearings or supports 24, carried by the adjustable support 23.. The arm 65 ofv such bell-crank lever is slotted at 65a for engagementvwith the roller 64V mounted on the pin 64, carried byjthe block 62, and the latter `may rock on the rod r52. In lieu of providing rockingblocks such asf illustrated. at 62; each carrying a pin k64 provided with a roller 64a adapted to the slots 65 formed in the arms 65 of the bell-crank levers- I may provide a collar 62a fixed to therod52 and carrying a pin 64b with a roller. 64c cooperating with the slot65a of said bell-crankvlever `65, as illustrated in Fig. 9.l yThe opposite end 68 of the bell-i crank lever'is :connected by av ball and socket joint,v orother universal connection 69, with. an

adjustable ylink 70, having asleeve 'Il at its opposite end slidably mounted .upon a `guiderod 72, supported in suitable brackets or supports '73 the frames carrycarried byand extending `upwardly from an 'ioperatingshaft `'74v mounted in*k bearings '75 on the table 111. The sleeve portion '71A of eachlink '70 isfelongated'r so asnto provide suiicieht vbearing Awith the/rod'72 to slide easilylthereinwhenthe 1 parts are moved by the operation yof the hand levers 55.
